RUBBER-SOLED SHOE.

SPECIFICATION forming part of Letters Patent No. 631,283, dated August 22, 1899.

Application filed November 23, 1893. Serial No. 697,296. (No model.)

T at whom it may concern:

Be it known that I, WILMER DUNBAR, a ci t-izen of the United States, residing in the cityof Akron, county of Summit, and State of Ohio,

have invented a certain new and Improved Rubber-Soled Shoe, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

My invention relates to shoes having rubber soles or tread-surfaces, to the soles themselves, and to the means for attaching such soles or tread-surfaces to the bottoms of ordinary shoes. It also relates to the details of construction hereinafter described and claimed.

Shoes have heretofore been made with a rubber sole or tread-surface screwed or cemented to the bottoms of the ball and heel of the shoe; but these have been unsatisfactory because of the labor of attaching, because the screws did not wear away as fast as the rubber, and would thus catch in carpets, rugs, &c., and because the cement did not hold. Rubber tread-surfaces have heretofore been secured to the shoes by leather borders or binders extending all the way around the tread-surfaces of the shoe; but this construction has the disadvantage of presenting a leather instead of rubber surface to the ground at the front and back or wearing-points of the shoe, thereby increasing the danger of slipping, and thus negativing one of the advantages of the use of a rubber tread-surface.

One of the objects of my invention is to avoid the above defects.

In the drawings, Figure 1 is a side and Fig. 2 a bottom view of a shoe embodying my invention. Fig. 3 is a detail sectional view of the heel of the shoe, showing the method of attaching the rubber thereto. Fig. 4 is a detail perspective view of the rubber portion of the heel removed from the shoe and inverted. Fig. 5' is a detail perspective view of the leather border or binder for fastening the rubber heel to the sole of the shoe.

Similar figures relate to similar parts throughout the several views.

As the method of construction is substantially the same for both the heel and ball of the shoe I, will first describe the heel portion. I mold the rubber portion 11 from soft rubber in substantially the shape shown in Fig. 4. This rubber heel has on the bottom the right-angled recess or marginal depression 12, extending across the front (the part next the instep) of the heel and about half-way back on each side. In practice I make the width and breadth of the rubber heel the dimensions of the'heel it is intended for and the thickness about five-sixteenths of an inch. The recess or depression 12 is about three-eighths of an inch wide and one-quarter of an inch deep, leaving the rubber wing or flange 13 about one-sixteenth of an inch thick; but these dimensions may be varied within wide limits Without departing from my invention. I reinforce this heel, and particularly the wing or flange 13, byjcementing a piece of canvas 14 to its upper side. I next make the leather binder 15 adapted to fit in the recess or depression 12 of the rubberheel. The thickness of the leather binder 15 should be at least a sixteenth of an inch less than the depth of the recess 12. I now coat with cement the bottom of the leather heel 16 of the shoe and place the rubber heel 11 upon it. I then place the leather binder 15 in the recess or depression 12. I then drive pegs or nails 17 through the binder 15 and the can vas-reinforced wing or flange 13 into the leather of the shoe, thereby securely fastening the rubber heel to the leather heel. As the rubberis at least one-sixteenth of an inch thicker than the binder 15, it extends down below the binder, and only the rubber is exposed to the ground, thus making the heel for all practical purposes a solid rubber heel. As the leather binder only extends partway back on the heel, the rubber at the rear may be worn away shape of the rubber sole and leather binding being proportioned substantially as shown in the drawings.

Having thus described my invention, what I claim as new, and desire to secure a Letters Patent, is

1. In a rubber-soled shoe in combination with the leather base of the shoe, a rubber tread-surface having in its lower edge a marginal recess or depression extending part way around it, a leather binder of less depth than the depression adapted to fit in said depression, and pegs or nails driven through said leather binder and rubber tread-surface into the base of the shoe.

2. In a rubber-soled shoe in combination with the leather baseof the shoe, a rubber tread-surface having in its lower edge a marginal recess or depression extending part way around it, canvas or other reinforcing material secured to said rubber tread-surface, a leather binder of less depth than the depression adapted to fit in said depression, and pegs or nails driven through said leather binder and rubber tread-surface into the base of the shoe.

3. A new article of manufacture consisting of the rubber heel of a shoe having in its lower edge a marginal recess or depression extending across the front of the heel and approximately half-way back on each side leaving a thin wing or flange of rubber above the recess.

4. A new article of manufacture consisting of the rubber heel of a shoe havinga strip of canvas or other reinforcing material secured to its upper surface and having in its lower edge a marginal recess or depression, extending across the front of the heel and approximately half-way back on each side, leaving a thin canvas-reinforced wing or flange of rubber above the recess.
